was able to bypass ventilation,luck me!

So far it is appearent that i wont need to ventalte my room becuse its a cistern that is basic cooled by the earth as it is pluged directly into the groung. 18 hrs of light
dosent even raise the temp 2 degrees in there. I have a fan pointed at my plants under the light and i leave the door cracked inorder to let fresh air in.
Based on all this I dont think I will ever need to ventalate the room, at least full; blwon ventaltion becuse i belive that haveing the door cracked and a fan blowing will suffice.
What do you all think about all this?

P>S I know the neighbors wont be able smell them when they bud becuse of how the sir is kept seprate from the outdoors.

IF you've ever had a set up simular to mine here please post some tips and tricks on how you make the most of your get-up.thanx!

what light are you using?

1000wt mh bulb

also are you giving any type of CO2 to your plants?

nope, just circulate the air around thoough.

c02 would let you have a completely sealed room...... stale air is no good in the long run and will show some wear and tear on the room eventually..... Never underestimate the smell of your poison.....
